Abstract

A method for transmitting and receiving a signal in a wireless communication system and an apparatus therefor are disclosed in the present disclosure. Specifically, a method for transmitting and receiving a signal by a receiving apparatus in a wireless communication system, according to an embodiment of the present disclosure, may comprise the steps of: continuously receiving a plurality of reference signals from a transmitting apparatus; sorting the ranges of channel phases on the basis of the plurality of reference signals; grouping the ranges of the channel phases into two or more groups; and receiving a data signal from the transmitting apparatus.

The invention claimed is: 
     
       1. A method for transmitting and receiving a signal by a receiving apparatus in a wireless communication system, the method comprising:
 continuously receiving a plurality of reference signals from a transmitting apparatus; 
 sorting ranges of channel phases based on degrees of phase rotations of the plurality of reference signals received compared to a first received reference signal among the plurality of reference signals; 
 grouping the ranges of the channel phases into multiple groups, wherein a number of the multiple groups is based on a specific number of bits of data signal to be received; 
 generating a basis of spatially aggregated phase modulation (SAPM) as a combination of a range of a channel phase from each of the multiple groups; 
 receiving, from the transmitting apparatus, a data signal with the specific number of bits, wherein each of the bits of the data signal is phase rotated at an interval for a rotation phase unit of the plurality of reference signals; and 
 decoding the data signal using the basis of the SAPM. 
 
     
     
       2. The method of  claim 1 , wherein the plurality of reference signals are configured by phase rotating the plurality of reference signals at regular intervals based on an arbitrary reference signal. 
     
     
       3. The method of  claim 2 , wherein the regular intervals are related to the number of bits of the data signal. 
     
     
       4. The method of  claim 2 , wherein the arbitrary reference signal is preset between the transmitting apparatus and the receiving apparatus. 
     
     
       5. The method of  claim 1 , wherein each group of the multiple groups include four ranges of the channel phases. 
     
     
       6. A receiving apparatus for transmitting and receiving a signal in a wireless communication system, the receiving apparatus comprising:
 a transceiver; and 
 a processor operably coupled to the transceiver, and configured to: 
 continuously receive a plurality of reference signals from a transmitting apparatus; 
 sort ranges of channel phases based on degrees of phase rotations of the plurality of reference signals received compared to a first received reference signal among the plurality of reference signals; 
 group the ranges of the channel phases into multiple groups, wherein a number of the multiple groups is based on a specific number of bits of data signal to be received; 
 generate a basis of spatially aggregated phase modulation (SAPM) as a combination of a range of a channel phase from each of the multiple groups; 
 receive, from the transmitting apparatus, a data signal with the specific number of bits, wherein each of the bits of the data signal is phase rotated at an interval for a rotation phase unit of the plurality of reference signals; and 
 decode the data signal using the basis of the SAPM.
